WHEEL CONSTRUCTION.

Application filed. November 16 1925.

This invention relates to sheet metal wheels, rollers, pulleys or the like, and has for an object thereof the provision of broadened reinforced hearings in the hub ends for the customary hub sleeve or barrel. Another object of the invention is the provision of a novel and eflicient cap retaining feature for the outer hub ends of wheels of this character.

The invention is fully described in the following specification, and while in its broader aspect it is capable of embodimentin numerous forms, one embodiment thereof is illustrated in the accompanying drawings, in which,-

Figure 1 is a central sectional View of a wheel or the like embodying the invention with the section longitudinal to the axis. Fig. 2 is a perspective view of the cup member forming a part of the invention before being inserted into a wheel disc, and Fig. 3 is a fragmentary section of the central portion of one of the wheel discs with the lining cup member for the disc opening in a initial position therein.

Referring to the drawings, 1 designates what will hereinafter be referred to as a wheel, but which may be a pulley, roller or the like. This wheel is of the disc type and includes the two opposed inner and outer discs 2 and 3 of sheet metal. These discs, as is customary with wheels of this type, have their central portions outwardly pressed in cylindrical form to provide bear ings for the respective ends of the usual hub barrel 4, said outwardly pressed portions, in the present instance, being in the form of outwardly turned annular flanges 5.

A cylindrical bearing member 6, in the present instance of cup form and having its open end provided with an outwardly projecting flange 7, is fitted into each bearing flange 5 of the wheel discs from the inner side thereof, being of suitable size for such purpose, and has its edge flange 7 in stop engagement with the adjacent inner side edge portion of the respective disc. When the member 6 is inserted into a bearing flange 5 with its flange 7 in stop engagement with the inner side of the associated disc, the outer end of the member 6 projects a sufficient distance beyond the free edge of the flange 5, so that when the sidewall portion thereof beyond the flange 5 is outwardly doubled by an inward compress- Serial No. 69,315.

ing force on the outer end of the member, said doubled wall portion will form an annular radially'projecting flange 8 at the outer end of the flange 5 in contact therewith and of a radial depth to project a distance beyond the outer circumference of said flange. The provision of the flange 8 is not only for the purpose of opposing the flange 7 in its engagement with the wheel disc flange 5, but is also for the purpose of providing a radially projecting portion of greater diameter than the flange 5, and in. outwardly spaced relation to the body of the associated wheel disc, with which the open end of a hub cap 9 may be engaged.

This cap, which is of the usual cup form, has its free edge split at intervals, as shown at 10, to provide an annular series of tongues around the cap edge for springing engagement over the flange 8. The cap 9 is preferably adapted to be forced a surficient distance over the flange 8 for the inner cap edge to engage the disc 3, and the cap is yieldingly held in this position by the provision of an annular recess 11 which forms a seat for receiving the edge of the flange 8.

The outer end of the bearing member 6, which is inserted within the outer disc bearing of the wheel, is provided with a central opening 12 of a size to permit the insertion of the outer end portion of a hub axle therethroughwhile the member 6 at the inner side of the wheel is preferably provided with a central opening 13 of a size corresponding to the inner diameter of the barrel 4, so as to permit the assembling of an antifriction bearing unit 14 within the hub barrel. It is apparent that the openings 12 and 13 may be formed in the bearing members 6 either before or after they have been secured to the wheel discs, and that the annular flanges formed by the walls of said openings project within the cylindrical vided with a central opening comprising an annular member with outwardly extending flanges secured in the disk opening and having inner and outer engagement with the disk to retain itin position therein and 'l'orining' at its outer end a hub cap holding portion, and a hub barrel mounted in said annular member.

2A h ub construction for disk wheels provided with a central openin comprising a sleeve in said opening, outwardly e:;

tending flanges on said sleeve at the inner and outer ends of said opening to retain the sleeve rigidly in position, said onter flange being spaced from the outer side portion of the Wheel and forming an anchorage for a hub cap, and a hub barrel disposed in said sleeve;

3. A hub construction for disk wheels naving a pair of bod-y disks provided with aligned hub barrel receiving openings, com prising'asleeve'i n each of said op rings, outwardly extending flanges on said sleeve at the inner and outer ends of the openings to retain said sleeve rigidly in position, one fie igebeing spaced from the adjacent outer sideportion of the respective disk and form an anchorage for hub cap, and a hub barrel mounted at its ends in said sleeve, said sleeves having inwardly projecting portions for eoacting with the respective barrel ends to prevent ar-zi al movement of the barrel in the sleeves.

l. A hub construction for disk wh els havmg opposed bod y disks, comprising outwardly extending flanges on the inner edges of the body disks forming hub barrel receiving openings, a sleeve disposed within each flange and anchored against axial move ments therein, a radially projecting portion on one end oi said sleeve extending beyond the adjacentfiange, a hub cap having snap holding engagement over said projecting portion of the sleeve, and a hub barrel having its ends mounted in said sleeve, and being held against axial movementby the outer portions 01 the s eeves.
